Özet: Çatalan Baraj Gölü’nün (Adana) Copepoda ve Cladocera (Crustacea) faunası. Çatalan baraj gölünün Cladocera ve Copepoda (Crustacea) faunası Temmuz 2001 ve Haziran 2002 tarihleri arasında aylık periyotlarla alınan örneklerin incelenmesiyle belirlendi. Örneklerin değerlendirilmesi sonucunda, Çatalan baraj gölünde kladoserlerden 8, kopepodlardan ise 2 olmak üzere toplam 10 tür saptanmıştır.

Anahtar Kelimeler: Crustacea, Cladocera, Copepoda, Çatalan Baraj Gölü.

Abstract: Cladocera and Copepoda (Crustacea) fauna of Çatalan dam lake were studied by monthly sampling between July 2001 and June 2002. Examination of the samples revealed a total of 10 species composed of eight cladoceran and two copepod species.

Introduction constructed across River in order to prevent flooding and is benefited for irrigation, drinking water and energy Although Cladocera and Copepoda fauna of Turkish inland supply. The water accumulation studies were started in 1996. waters have been intensively studied (see Ustaoğlu, 2004 for The lake is situated at North of Adana province and 25 km complete review) there are still many water reservoirs that are away from Çukurova University campus area. in need of investigation, such as dam lakes, rivers and that especially high altitude lakes which can reveal new faunistic records (Ustaoğlu et al., 2005). Cladocera and Copepoda fauna of Çatalan dam lake have not yet been studied. The aim of this paper was to determine Cladocera and Copepoda fauna of Çatalan dam lake and hence contribute to the fauna of Turkey.

Material and Methods

Sampling was made monthly at five different stations between July 2001 and June 2002 (Figure 1) in order to determine the

Cladocera and Copepoda fauna of Çatalan dam lake. Samples were collected with a 55 µ pore sized Hydro-Bios Figure 1. Çatalan dam lake and sampling stations. plankton net by horizontal and vertical hauls and the specimens were immediately preserved in 4 % formaldehyde. The Cladocera and Copepoda species were identified Results and Discussion according to Einsle (1996), Lilljeborg (1900), Negrea (1983), Temperature, pH, dissolved oxygen and secchi depth Smirnov (1974), Ueda and Reid (2003). Martin and Davis parameters were measured monthly between July 2001 and (2001) was followed for higher classification of the species. June 2002. Physical and chemical parameters determined in Water temperature and pH were measured by using Çatalan dam lake are given in Table 1. Sampling could not be Hanna HI 9025 microcomputer pHmeter; oxygen was made due to unfavourable weather conditions in December measured by YSI-55 oxygenmeter; turbidity was measured by 2001. Unfortunately oxygenmeter probe was broken down in a 25 cm diameter secchi disc. November 2001 therefore dissolved oxygen parameter could Çatalan dam lake (Figure 1) is an important inland water not be measured in the following months. reservoir of Southeast of Mediterranean Region which 428 Aladağ et al. / E.Ü.
